my science book says to use the "inv" key when adding vectors but no calculator I have has that, do I need a special calculator or is it under a different symbol?
+130513 I'm not familiar with any key that adds/subtracts vectors.....but.....you really don't need one, anyway......when adding or subtracting vectors, we just sum (or subtract) their respective components....for instance....
< 1, 2 > + < 5, 7 > = < 6, 9 >
And
< 7, 3 > - < 10, 13 > = < -3, -10 >
Does that make sense ???
